Claims.

This invention relates to filling winding machines of the type having a plurality of winding spindles or units and relative motion between the winding units and a part-of or place in the machine at which the winding units are succe'ssively tended. Machines of this type are described and claimed in United States Patent No. 2,160,810, and in application Serial. No. 386,136, filed March 31, 1941. This invention is particularly applicable to the preferred form of such machines in which a plurality. of filling winding units are moved in a procession during winding, this procession passing automatic mechanism adapted to replace the wound package on each unit with a new empty core and start the winding of a fresh filling wound package on such new core as the unit passes, such machines being shown as preferred embodiments of said patent and said application Serial No. 386,136. Among the objects of the invention are to simplify and improve the mechanism for producing the filling wind on the several units of the machine; particularly to simplify the construction of each of the several winding units; to simplify and improve the mechanism for determining the progressive shifting of zones of traverse of the thread traversing means of the several units; and to utilize for this purpose the relative traveling movement between the winding units and other parts of the machine.

Other objects of the invention and features of advantage and utility will be apparent from this specification and its drawings wherein the invention is explained by way of example.

In the drawings: Fig. 1 is a plan view of a traveling spindle winding machine having the present invention applied thereto, this view being simplified by the removal of numerous parts not directly involved in this invention and by the omission of all ex- Fig. 5 is a side elevation of the winding unit of Fig. 4;

I Fig. 6 is a fragmentary vertical sectional view, taken on the line 6--6 of Fig. 4;

Fig. '7 is a fragmentary view showing the thread guide assembly, taken on the line 1-1 of Fig. 6; and

Fig. 8 is a fragmentary vertical section of the friction slider element of the thread guide assembly and the reciprocating rod for driving the latter, taken on the line 8-8 of Fig. 7.

The winding machine, as to its general organization and construction of frame, winding unit conveying means, and winding unit tending mechanism, may be substantially the same as shown in said application Serial No. 386,136.

Thus the machine is shown as having a suitable guideway comprised of upper and lower rails H and I2 (Fig. 2) which define opposite straight and semi-circular runs (Fig. 1) for the winding units, and are supported by suitable frame sections l3 (Fig. 2). An endless chain I4 connected to the several traveling winding units, runs on suitable sprocket wheels l5 at opposite ends of the machine, one such sprocket wheel being driven by a motor not shown.

As shown in Figs. 4 and 5 (which are generally similar to Figs. 18 and 15, respectively, of said application Serial No. 386,136), the head portion of the winding units includes a frame element connected to the chain I4 by pivoted link I4" (Fig. 4) and carrying suitable rollers 4|, 42 and '43 adapted to guide the unit along the upper rail ll.

A generally vertical frame element extending from the upper frame element 40 down to the lower rail l 2 carries a suitable support 52 for cept two of the numerous traveling winding units of the machine;

Fig. 2 is a right end elevation of the machine of Fig. 1 with certain parts broken way, and partly in section and with all excepting-one of the winding units omitted;

Fig. 3 is a fragmentary plan view, partly diagra mmatic, and with numerous parts omitted, showing four of the winding units of the machine at the place where the bobbins are changed and the winding started on the winding units in succession;

Fig. 4 is a plan view of one of the winding units of a machine, on a larger scale, with its winding package partly finished;

for the guide wires and tension device which act on the yarn leading from the supply package.

Referring to Fig. 4 a hollow driving head 6|) adapted to receive the base of the winding bobbin and having a serrated rim BI is driven through a shaft 62 from an electric motor indicated generally at 63. A reciprocating traverse rod 66 is driven with a short stroke of traverse (only a small fraction of the length of the final length of the wound bobbin) through cam mechanism also operated by the motor 63. As shown in Fig. 4 the motor shaft 62 carries a worm l0 meshing with and driving a cam wheel 12 through teeth 13 on the periphery thereof. The cam wheel 12 is provided with a double throw cam groove 14 of appropriate shape.

Preferably the cam 72, worm l0, and shaft 62 traverse rod 60.

are mounted in a casing secured to the frame element 40, this casing having integral therewith a cup-shaped portion 00' surrounding and holding one end of the motor 00. The traverse rod 00 extends into the casing 00 through a slot (Fig. '4) and inside the casing is connected at its inner end to an arm 0i, pivoted at 02 and carrying a cam-follower roller 00 which lies in the cam groove 14.

The outer center I00 for holding the outer end of the filling bobbin is mounted on a plunger Hi0 which is slidable in an outboard bracket I00", this bracket being fixedly secured to a horizontal bar l00 rigid with the frame 40 of the winding unit. The outer center I00 is normally forced against the winding bobbin by a spring (not shown) in the bracket I00, and may be retracted by a bell crank I00 of which one arm engages the plunger I00 within the bracket. When the winding unit reaches the bobbin-changing apparatus of the machine the outstanding arm of the bell crank I00 engages a stationary angle piece 590 (Figs. 3 and 5) and is moved thereby into the dotted line position of Fig. 4 (as in the case of the two winding units at the left of Fig. 3) .thus retracting the center I00 and releasing the bobbin. At the right-hand end of the stationary angle piece 590 (Fig. 3), the bell crank I 00 is released and the plunger I00 and center I00 return to their normal positions, the center I00 thus engaging an empty bobbin presented to it by a magazine diagrammatically indicated at H2 in Fig. l. The position of a bobbin held by the magazine is indicated by the center line X-X in Fig. 3, the bobbin being grasped between the centers at this place.

For the purpose of this invention the magazine may be of any suitable construction to supply fresh bobbins to the several winding units in succession, and the magazine may for example have the construction of the magazine I I2 of Figs. 2 and 4 of said application, or may embody the improvements as to feeding and delivery of bobbins shown particularly in Figs. l3, 14, 21 and 22 of said application. For simplification of illustration the bobbin magazine is indicated only diagrammatically in this application.

The thread guide assembly T (Fig. 6) is shown as mounted on the reciprocatingtraverse rod 66 in frictional engagement therewith so as to be movable back and forth with the reciprocating movement of the traverse rod 60 but capable of being slid on the traverse rod 66 so as to be advanced along the traverse rod.

Referring to Figs. 4, 6, '7 and 8,. the thread guide assembly '1' may for example comprise an upper plate I above the traverse rod 56 and carrying the eyes I 45 and I49 by which the thread respectively enters and leaves the thread guide assembly and a lower plate I50, below the traverse rod 56, these upper and lower plates serving to retain between them vertical spacer members I52, I52, preferably of fiber or other friction material surrounding and frictionally engaging the The frictional grip of the thread guide assembly upon the traverse rod 66 is preferably increased by the provision between the two plates I and I 50, of a tubular jacket I54 of cork or other frictional material surrounding the traverse rod and held in frictional engagement therewith by a surrounding tubular element I55 having springlike fingers I56 (Fig. 8) which hold the cork friction element firmly around the traverse rod 66. A downtumed extension 491 on the upper plate of the thread guide assembly carries a guide roller 03 adapted to run looselyin a groove in the horizontal frame member I00c (Fig. 6) thus positioning the thread guide assembly against rotation around its round" traverse rod 00.

It will be seen from the above description that in a preferred form of the invention there may be employed the general construction of the frame, conveying mechanism, rotary bobbin holding centers and mechanism for opening and closing them to discharge full bobbins and take fresh bobbins that is described in said application. as well as mechanism similar to that described in said application for imparting a short stroke of traverse to the reciprocating threadtraversing means on each winding unit.

The machine illustrated in this application differs from that of said application Serial No. 386,136 principally in an improvement in the mechanism for determining the progression of the thread traversing means of the several units, as will now be explained.

In both the aforesaid patent and application each winding unit was provided with feeler mechanism for causing the thread guide assembly to advance along the traverse rod so as to produce a filling wound bobbin growing from the base to the tip end of the bobbin. In a machine according to the present application, however, such feeler mechanism is rendered unnecessary because the relative movement between the winding units and other parts of the machine is utilized to determine the progressively shifting zones of traverse of the thread traverse means from the base or beginning end of the bobbin to the tip end.

Referring to Figs. 1, 2, 3 and 5, the preferred form of mechanism involves a stationary camlike structure extending around the machine and acting an an abutment to determine the zone of reciprocating traverse of the thread guide assemblies of the several winding units, such that starting at the beginning of winding of a package the zone of traversing is in a relatively short zone near the base end of the bobbin and then is progresslvely shifted along the bobbin until it finally reaches nearly the tip end of the bobbin.

Referring to Figs. 4, 5, 6 and 7, the thread guide assembly T preferably carries on its upper plate I an upstanding post I10 having thereon a roller I'II. During the travel of the winding units around the machine the zone of traverse of roller Ill and hence of the thread guide assembly T is determined by a non-traveling cam-like structure preferably consisting of two vertical flanges 000 and SM, spaced apart a distance such that travel of roller ill from one such fiange to the other will produce the desired length of traverse stroke of the thread guide assembly. The distance between these flanges 600 and 60I may for example be such amount as 1 inch, 1% inches, 1% inches, 2 inches, or the like, depending upon the desired length of stroke of traverse.

Referring to Figs. 1 and 3 it will be observed that, starting at the line Y-Y where the regular stroke of traverse begins, these two flanges 800 and GM are located adjacent to the base or butt end of the winding bobbin; and that proceeding around the machine in the counterclockwise direction of travel of the winding units, these flanges 600 and GM are gradually located farther and farther away from the base or butt of the bobbin and nearer to the tip end thereof, finally attaining, at about the line Z-Z, a position adjacent to the tip end and quite removed from the base or butt end. The zone of traverse of the thread guide assembly of each winding unit is determined by the position of the unit on the track.

Thus the typical filling wind is produced, with the yarn laid in many nested conical layers and with the final such conical layer several inches away from the first layer of winding and from the base or butt end of the bobbin.

It will be observed that this principle of using the relative travelling movement between the winding units and other parts of the machine to determine the progressive advance of the zone of winding of the filling wound bobbin greatly .simplifles the construction of each .winding unit.

No feeler mechanism is needed on any of the winding units to govern the advance of the thread guide assembly. And without such feeler mechanism should the yarn break duringthe winding, there is no possibility of the feeler chafing the body of yarn that was wound prior to breakage. Accordingly, no detector-controlled stop mechanism is needed on the several units.

At the line Z-Z at which place the winding of each successive bobbin has been completed, the machine preferably includes means similar to that described in said application Serial No. 386,136 to return the thread guide assemblies of the successive units to the base or butt end position in aid of associating the thread extending from thread-guide eye I49 with the hollow center 60. Such means can in the present machine conveniently comprise an inclined extension 473 of the outer flange Gill adapted to act upon the roller lll to carry the thread guide assembly from the final outermost position to a position where the traverse assembly lies near the inner hollow center 60. This extension 413 is preferably continued parallel to the path of travel of the winding units; as shown in Figs. 1 and 3, in the zone where the bobbin magazine H2 is encountered. Then, after the bobbin'magazine has been passed, a further inclined guide extension 413 comprising two downturned flanges relatively close together is adapted. to receive the roller ill of each unit, and lead it and the thread guide assembly into position for the thread guide to distribute the thread in the form of a bunch on the bobbin while the roller I'll passes from the YY is reached, the bunch then being complete,

the motion of the thread guide assembly passes under control of the two flanges 800 and 6M spaced apart as described above by an amount such that the thread guide can make its full stroke of traverse for winding a filling wound bobbin.

Inthe preferred form of the invention illustrated herewith where the abutment which controls the progression of the zone of traverse is in the form of a pair of flanges 600 and 6M, the inner flange 800 imparts the progressively advancing movement to the thread guide and the outer flange is available to preclude any undesired movement of the thread guide outwardly beyond its intended zone of traverse.

We claim:

1. A winding machine having therein, in combination, a plurality of filling winding units each including a thread-traversing means, an abutment for cooperating with said plurality of filling winding units, and means for causing a relative traveling movement between said plurality of filling winding units and said abutment, said abutment being shaped and located to act on the thread-traversing means of the several units to define a progressive shifting of the zone of traverse from the base to the tip of the filling winding package during said relative traveling movement.
